STATES PATENT OF IPHUS H. HALL, JR, OF LYNDON, VERMONT, ASSIGNOR TO TELEPHONE TOLLMETER COMPANY, OF ST. JOHNSBURY, VERMONT, A CORPORATION OF VERMONT.

TIME-GLASS.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed April 12 1906. Serial No. 311,265.

To all whom it may concern:

Be it known that I, IPHUs HARVEY HALL, Jr, a citizen of the United States, residing in Lyndon, county of Caledonia, and State of Vermont, have invented an Improvement in Time Glasses, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawings representing like parts.

This invention has for its object the pro. duction of a novel time glass.

In the use of telephones, the rate in long distance and toll lines depends upon the time that the telephone is employed, and usually three minutes is allowed for a conversation, and after that time an extra charge is made. A person using a telephone is frequently so engrossed in the communication that it is de sired to make, that the idea of time is quite forgotten, but by the use of the device herein to be described, the limit of time may be readily and easily determined. The device may be used for other purposes than in connection with a telephone.

Figure 1 in perspective shows my time glass and its novel sustaining means; Fig. 2 is a section in the line ;t,.,Fig. 1, and Fig. 3 represents the blank from which the holder will be formed.

Referring to the drawing, A represents a time glass composed of a tube of uniform diameter contracted between its ends that it may be engaged by a holder B revolubly mounted in a support O, the holder having a foot co-acting with said support in such manner as to retain the glass in operative position, either end up. The time glass is shown as provided with a mass of finely pulverized material A which may be sand, and the contracted part A of the glass, see Fig. 2, has a small hole of a size to determine the ,amount of time required for the sand or other medium to pass from one end of the tube through said small hole into the other end, the time in this present instance of my invention being considered about three minutes, but it might be any other length of time according to the requirements for the use of the time glass. The support O is represented as a metallic plate having a central hole and struck to form a raceway O for the foot B of the holder B. The holder is shown as comprising spring fingers, extended from a circular foot.

Referringto Fig. 3, which shows the blank from which the holder is formed, it will be noticed that each arm of the blank is bent on the dotted lines 11, 22, and 33 to form the part b that is laid on the foot 1). Bending the arms as shown, results in the parts 4 of said arms between the lines 3 and 5 being held yieldingly together while the parts 6-7 are shaped to embrace the time glass at its smaller diameter leaving the ends of the arms of the holder B to be grasped between the lingers when it is desired to turn the holder in the support. To place the holder in its operative relation to the support, the ends of the arms of the holder B will be inserted through the support C from its rear side, and thereafter the time glass will be forced between the spring arms of the holder. This invention is not, however, limited to the precise shape shown for the holder, as I consider within the scope of my invention any holder that will engage and so sustain. a time glass that the holder may be revolved in the support. The form of holder herein shown, however, possesses advantages, one of which is that its free ends may be sprung apart sufficiently to enable the time glass to be withdrawn from the holder that it may be packed with the rest of the apparatus snugly in a box for shipment.

The support C will preferably be connected with the side wall or other upright near the telephone, and the support is shown as being set upon a piece of fiber or other frictional surface D, and to retain the foot frictionally in any position that it may be left due to adjustment, I prefer to use a fiber or leather Washer as D so that the foot on the holder is acted upon at both sides by friction means.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with a support, of a holder presenting a foot revolubly sustained by said support and resilient arms extending laterally from the foot, and a time glass sustained at its central portion by said arms.

2. The combination with a support, of a holder presenting a foot revolubly sustained by the support and resilient arms extending laterally therefrom, said arms each having intermediate of its ends a glass-receiving recess, and a time-glass sustained centrally by said arms and occupying the recess therein.

3. The combination with a support, of a holderQ having -a foot revolubly sustained thereby, said holder also having two laterally-extending arms, of a time glass sustained by said arms intermediate of its ends, the extremities of the arms constituting a handle by means of which the holder and time glass may be turned.

4. The combination with a support having a struck-up annular portion (3 of a holder presenting a circular foot received in said annular portion (3 and two resilient arms extending from the foot, each having a glassreceiving recess and a time glass centrally sustained by said arms.

5. The combination with a support having a struck-up annular portion C, of a holder presenting a circular foot received in said annular portion C and two resilient arms extending from the foot, each having a glassreceiving recess and a time glass centrally "sustained by said arms, and frictional material between the foot and the struck-up portion that frictionally holds the holder in position.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
